This invention relates, to that type of vend ing,` machinegwhich `at one operation vends the entire contents of its magazine, most commonly a single package, andknown as a unit vender. A machine ot this type maybeot small dimensions and yet vend apackageot considerable size, and the operatingI mecha nism ot the machine .may be simple in construction. For example, the machine of this invention mayvcnd a lnackage of razor blades, conlections, or other. suitable articles. Because oit its small dimensions a bank or series oit such machines may be conveniently ar ranged, all ot which may vend the saine` kind ot articles ora variety of 4articles ci difieren kinds, as may be desired..

Heretoiore vending machines of this type have been more or less complicated in construction, liable to derang'ement, `expensive to manufacture, insecure against theft` of the contents or, of the machine itseli",` and in some ceses inconvenient tor the attendant to replenish the magazine and remove the coin.

@bj/acts of this invention are to provide fan r improved vending machine ot this type of simple and inexpensive construction, reliable and eliective in operation, atiordingr security against theft of the contained package or of the machine itself, and convenient and timesaving for the attendant tomanipulate, totether with other objects and advantages which will hereinafter appear.

The inventionincludes,various features ot construction and combination :oit parts, 4as will appear from theffollowingg description.

The embodiment of the invention shown in the accompanying; drawings will now be c escribed and thereafter the invention will be pointed out in claims,.re'ference now being hadAt-o the drawings, in which:

The vending .machine construction Aby which the invention is carried ont according to the embodiment thereof illustrated in. the accompanying drawings will now beparticularly described.

An upright rectangular casing; bon7 open at the front and having' a rear wall l, side walls 2 and 3, a bottom wall e, and a top wall may be formed by stamping1 and welding` opera- `tions trom suitable sheet metalsuch as steel. An outer front doorI plate or wall6,iwhich may be a die casting, is hinged at itstop to A,the topwall 5 ot' the casing box hvmeans of ahinge pin 7 which is headed.atbothends to Atorin a rivet. The door t5 carries inner `wall or plate 8 to term in ett'ectza` part thereof spaced therefrom somewhatmore than :the thickness ot' a proper coin and firmly secured thereto, such as by meansot rivetsQ (Figs. rl and 5), these rivets passing,` throughbosses or lugs on the inner side ofthe outer door wall 6 against whiehthe inner `wall p8 abuts, the margins ot this inner wall 8 fitting1 into an inner marginaliiange.provided on `the outerwall 6, aswillbe clear i'romthe drawings. Theinner and` outer walls 6 andSof the door are further securedtogether `against possibilit;7 of spreadingbymeans ot a fifth rivet l0 adjacent the lett side thereof and` its outer bottom wt ll i and at its lateral inargins is iiangred downwardly thus to restb7 its iianges on the outer bottom wall, this inner `bottom wall 11 boiling;n shownas held firmly in place by means oi rivets l2 and 13 which pass across the intervening space between these bottom Walls, adjacent the front and rear and on a middle line between the side walls 2 and 3. An inner rear wall 14 for the casing boX is spaced from the outer rear wall 1 thereof and its margins are firmly secured to the side walls 2 and 8 and top wall 5, as shown in Figs. 2 and 4, thereby providing a rear space which may be utilized, as will hereinafter appear. The rectangular space enclosed by the side walls 2 and 3, top wall 4, innerv door wall 8, inner bottom wall 11 andy inner rear wall 14 forms a magazine chamber to receive a package 15 (Figs. 2 and 4) of goods to be vended. Information as to the kind of goods contained in the package 15 may be supplied to customers by means of a suitable card (not shown) or slip of paper, which also may havethereon any other information or advertising matter desired, beneath atransparent name plate 16, which may be of celluloid, held in place by a frame or holder 17 secured to the top wall 5 and which may be a brass stamping.

Normally, or when the magazine chamber contains a package 15 to be vended, the door 6 is locked inclosed condition, as shown in Figs. 1 to 4 inclusive of the drawings, and can only be unlocked to give access to the magazine chamber for the removal of the package 15 by means of a proper coin 18 (Fig. 5), whichin'the particular machine illustrated in the drawings is a twenty-five cent piece, but of course similar machines may be constructed to be operated by means of a coin of anyl denomination desired and to vend packages of proportionate size and value. In carrying out the invention improved means are provided to prevent the loss of a proper coin in the machine after the latter has been `once operated and to prevent the loss of an Athe insertion of a proper coin; to prevent the removal of the inserted coin after the machine has been operated except by an authorized person; and to prevent the relocking of the door without the release of the coin and the insertion of another package into the machine.

The mechanism for locking and unlocking the door 6 will now be described. A forwardly extending outwardly cam-faced latch hook 19 is located between the bottom walls 4 and 11, so as to be inaccessible when the door 6 is locked in closed position, and is adjacent to the left side wall 2 with its outwardly camfaced, locking hook projecting towards the right. This latch hook is pivoted on a stud 2() (Fig. 8) which projects downwardly from Vthe inner bottom wall 11, the movement of this latch hook towards its locking position being limited by a tail thereon abutting against the adjacent flange of the wall 11, and it is pressed towards its engaging position by a wire spring 21 carried thereby and engaging the rear rivet 13, this spring being rigidly secured to the latch hook, such as by being seated and firmly gripped in a saw-cut slot therein. This latch hook yields to permit the locking of the door G, but is not moved in unlocking the door by means of a coin, and when the door is locked this hook is inaccessible, and hence there is no way or means by which this hook may be moved for thus in this way unlocking the door, without the insertion of a proper coin, as will now be described.

For locking the door G the latch hook 1S) may yield and snap its hook into engagement with the inturned rounded hooked end of a substantially vertically arranged coin-operated latch lever 22, which. in the construction shown, is a cam lever to be moved by a moving coin, such as the coin 18, out of engagement with the hook of the latch hook 19 for thereby unlocking the door Excepting at its lower inwardly cam-faced hooked end which projects inwardly through a slotted notch in the lower edge of the inner wall S of the door G, the latch lever 22 is located bctween the inner and outer door walls G and S towards the left side of the casing box and is a substantially straight lever of the lirst order pivoted slightly above the middle of its length on a pivot stud 23 which projects rearwardly from the outer door wall G (Figs. 2 and This lower lever or latch lever 22 is pressed towards its latch-engaging position by a wire spring 24 which at its lower end is rigidly secured thereto below its pivot, such as by means of being seated and firmly gripped in a saw-cut slot therein, and this spring extends upwardly above the lever pivot 23 and at its upper end abuts aginst the inner marginal flange of the outer wall G adjacent the left side wall 2 of the casing box. In the construction shown, the spring-pressed movement of the latch lever 22 is positiveljv stopped both at the upper and lower ends of this lever, at the lower end by the above noted slotted notch in the lower margin of the inner plate 8 in cooperation with a slot or notch formed between two of the above noted inner lugs which are on the lower end of the outer wall 6 (Figs. 2 and 3), and near its upper end the latch lever 22 may abut against a stop lug 25 formed on the inner face of the outer wall G and which also forms a stop to limit the downward movement of a proper coin such as the coin 18, as shown in Fig. 5 and as presently will be made more clear. At its upper end projecting above the stop lug 25 the latch lever 22 is provided with an inclined cam face 26 to be en ged by the adjacent circularly inclined lower lateral portion of the edge of the coin 1S as the coin is moved downwardly, thereby to rock this lever in a counter-clockwise direction, as viewed in Figs 1 and 5, against the tension of its spring 24 as shown in Fig. 5, which movement of this lil') llfi `the invention incassa leverwill disengageiits lower end from the will hereinafter appear, is a substantially straight lever of the first order substantially vertically arranged adjacent the lett side wall 2-ot the casingboir between the outer and rinner door walls t3 and 8 and is pivoted somewhat below the middle oi' its length upon the Vaforesaid pivoteforming rivet lO, which is located at about the middle ot the vertical length of the casing box. The adjacent ends ot the lower and upper levers 22 and 29 are pivotally locked together by means ot the teeth 27 and 28 and a downwardly projecting tongueor tooth 30 on the lower end ot the lockinglever 29 which has a somewhat loose engagement in the slot formed between the teeth 27 and 28 on the latch lever 22. The inner edge of the locking lever 29 forms a lateral guide for the adjacent edge of the coin 19 as the latter is moved downwardly by means presently described. At its lower end this lever 29 is provided with an inclined cam toe 8l which projects into the path ot the adjacent edge portion ot a downwardly moving proper coin, such as the coin 18, prior to the engagement ot the coin with the cam 'E tace 26 on the lower or latch lever 22, this cam toe projecting somewhat beyond the upper end ot' such cam tace in slightly vertically spaced relation thereto (Figs. l and 5). At its upper end at the right the locking lever 29 has a laterally projecting stop or abutmentlug 32 toi' a purpose which will presently appear. This upper lever is urged to rock in a counter'- clockwise direction as viewed trom the `front by means ot a downwardly extending wire spring 33 rigidly secured at its upper endto the lower end portion ot the lever, such as by be 1g firmly seated and gripped in a saw-cut slot, and at its lower tree end abutting against the marginal iiange oit' the outer door wall 6 adjacent the lett casing wall 2. Vihile the lower and upper levers 22 and 29 are posi- `tively connected together, it has been found desirable in the particular embodiment et shown to have individual springs for these levers rather than one spring in common.

A. locking pawl Bajautomatically engages the upperend et the locking lever 29 to prevent return movement ot this lever and ot' the latch lever 22 by their springs after these levers have been operated by a moving coin, as shown in Fig. 5. This pawl, which is between `the door walls 6 and 8, is pvoted adjacent the left casing `wall 2 on astud 35 projecting trom the wall 6. This pawl normal* -ly `restsiipon the upper end of thelocking lever29 `(Fig. l) landisnotched :as shownto engagethe adjacent-end cornerfol'the lever andbestopped therebyin engaging position `(Fifo. 5) and the pawl is shown as having an upwardly ,projecting arm by which its release from the lever may be effected, as will be hereinafter described. The locking pawl '34, wheniit is sopermitted by the coin-operated movement of, the locking lever 29,-is, activated to locking position by an upwardly extending `wire spring 36 rigidly secured thereto, such as by being firmly seated and i gripped in a saw-cut slot, and at its upper tree end abutting against the adjacent marginal `flange otthe outer door wall 6.

`Towards its upper end and right side the outer wall 6 of the door has a raised portion 37 on its outer side (Figs. l and 2) by which this wall is thickened. ceiving opening 38 oit a size to receive a proper coin, such as the coin 18, is provided in the thickened portion 38, through the outer; door wall 6 at a middle point transversely and having its lower edge at about a middle point 1 vertically of the wall.

A manually operable depressible coincarrying plate 39 is slidable vertically be tween the outer and inner door walls 6 and 8 and is guided at its right edge by the. adjacent flange ot the wall 6. A handle knob l() fixed onthe upper end of the slide plate 39 projects to the outside at the'front through a vertical slot All` in the thickened portion 37 of the 'front plate 6, this slot forming a guide and stops tor the coin-moving plate 39. The Coincarrying plate 39 when set tree at its lower position will be retracted or returned to its uppermost normal position by means of a two-armed wire `spring 42 having an upper i its end adjacent the right casing wall Spasses `freely through the inner end portion ol a stud or pin a5 which is rigidly carried by and projectsrearwardly fromthe coin-moving plate 39 through a vertical slot 46 in the inner door wall 8 and which also forms a guide and may provide additional stops tor this plate. The inner or rear side oit the outer door plate G is provided with a shallow vertically slotted groove 47 (Figs. 1 and 4t) to accommodate a head onthe pin 4:5 at the front of the slidable coin plate 39 for affording a firm and secure .connection of the pin 45 to the coin plate 39.

The coinfcarryingiplate39 is cut away or A circular coin-rethe opening 38.

recessed at its left side and lower end to receive the coin and to provide at the lower end of the main or body portion a coin-pushing shoulder 48 and a depending portion or leg 49 forming alateral guide for the edge of the coin opposite to the other lateral guide formed by the locking lever 29. The lower end of the leg 49 is provided at the left with a downwardly inclined coin-engaging lateral toe 50 which projects beneath the adjacent lower portion of the edge of the coin in spaced relation thereto when the latter is engaged by the shoulder 48, as in Fig. 5.

W'henthe coin-carrying plate 39 is at itsnormal retracted or uppermost position (Figs. l and 2) its coin-moving shoulder t8 clears and vis immediately above the upper edge of the coin opening 38 and its inclined toe 50 is spaced below this opening at the right side thereof while the opposing coin-guiding edges of the leg 49 and locking lever 29 are substantially flush with the lateral edges of The space between the tip of the toe 50 and the edge or" the lever 29 is such that a proper coin, such as the coin 18, inserted latwise `through the vopening 38 against the inner wall 8 will drop down for a part of its width between the walls 6 and 8 and rest uponthe toe 50, thus holding the coin in the machine Vpreparatory to a vendine` operation thereof.

Should a smaller coin be inserted it will drop past the toe 50 down between the walls and will be directed by the stop lug 25 at one edge of the coin and by an upwardly extending terminally inclined portion 51 of the lower inner lug boss or thickened portion of the outer plate 6, at the other edge of the coin. to a rejection opening 52 in the plate 6 through which it will be finally guided by a concave outwardly inclined lip 53 on the inner wall 8 and punched out therefrom, thus returning any such coins to the depositor.

Adjacent the locking lever 29 the coincarrying plate 39 has a. straight vertical edge 54: tern'iinating at the top in a square-cornered horizontal shoulder 55. With the coin-carrying plate 39 at its uppermost or normal position (Fig. l) its left edge 5l is closely adjacent to and in the path of movement of the stop lug 32 on the upper end of the locking lever 29, thereby to lock and prevent any substantial rocking movement of this lever in a clockwise direction, as viewed in Fig. l. By reason of the above described engagement of the tongue or too-th 30 on the lower end of this locking lever 29 with the right hand tooth 27 on the upper end of the latch lever 22, this locking of the locking lever 29 by the coin-carrying plate 39 causes this lever 29 to lock the latch lever 22 against disengagement from the latch hook l9 and thereby te lock the door 6 in closed condition, as shown most clearly in Fig. 3. rllhis locking of the latch lever 22 prevents the possibility of its being operated to unlock the door by the insertion of a probe such as a wire or the like down through the coin opening 38.

When there is a package l5 in the magazine chamber of the casing box and no proper coin has been inserted the coin-carrying plate 39 may be moved freely downward to any extent and will be returned to its normal position by its spring 42, this being merely an idle movement which accomplishes no result. lilith a proper coin inserted through the opening 38, downward movement of the coincarrying plate 39 will carry the coin downward resting upon the toe 50 of this plate until the edge of the coin comes into engagement with the cam toe 3l of the locking lever 29, waereupon further slight movement ot the coin-carrying plate 39 will bring its shoulder t8 into engagement with the upper edge of the coin. Should the handle knob l() be released at this point or at any point above this, the coin will merely be returned to its original position, to which it will be lifted by the coin plate toe 50 without operating the machine. In the particular constructic i shown and by reason of the relative position and relationship of the cam toe 3l on the locking lever 29 and the inclined cam ia e 26 on the latch lever 22, continued downwzrd Vmovement of the coin-carrying slide plate 39 will initiate a slight clockwise rocking movement of the locking lever 29 independently of the latch lever and which is permitted by reason ol2 the slight play or somewhat loose connection between these levers. Immediately after the lateral edge portion of the coin has thus engaged the cam toe 3l. the continued downward movement of the coin-carrying plate 39 will bring the circularly inclined lower lateral edge portion of the coin into engagement with the sloping or inclined cani face 26 of the latch lever 22, whereupon both. of the levers 22 and 29 will be rocked from their normal position shown in Fig. l to their coin-operated position shown in Fig. 5, in which they are locked by the spring-pressed locking pawl 3l. rlhis coin-operated movement of the latch lever 22 unlocks the door 6, as has already been described, while the locking of the latch lever 22 by the locking lever 29 and pawl 3st prevents the relooking of the door by reason of the fact that lfhe latch hook 19 is now ont of the path of the inturned hooked latch-engaging` lower end of the latch lever 22. Y

In the final part of the downward movement of the coin-carrying plate 39 substantially as the edge of the coin comes into engagement with the cam toe 3l the top shoulder 55 on this plate comes even with the abrupt or substantially horizontal lower face of the stop lug or hook 32 of the locking lever 29 and this lug is shifted into the return path of the coin-carrying plate 39 in spaced relation above its shoulder 55 with the locking lll() ltlfi ALi meeste lever 29 locked by the spring pawl 34C. In F the coin-carrying plate 39 is shown at its lowermost position and any further downward n'iovement ot the coin 18 is prevented by the stop lug with which the lower edge ot the coin has been brought into engagent' 51s soon as the customer releases the handle knob llt), the coin-carrying platefi@ will be raised by its spring l2 to the Llimited extent which will bring' its shoulder 455 against the ste lue' 3") which will thus (y, h A J wjp L, d

. substantially into Contact with the edge ot' the coin 18 while the coin 18 may remain in the position shown with the shoulder 48 in spaced relation to the upper edge ot the coin, in which case, in` the particular construction illustrated in the drawings, the toe 50 ot this plate will have been brought substantially into contact with the edge ot the coin 18, however, so tar as this part or the following parts ot the complete operation are concerned, it is immaterial whether or not this toe lifts the coin somewhat. Although the door of the casing boX is now in an unl cked condition and therefore accessible from both sides thereof, it is evident that the coin with which the machine was operated, such as the coin 18, will be retained between the door walls 6 and 8 againstunauthorized removal.

It is `desirable that the door 6 of the casing box when it has been unlocked as above described shall be automatically opened to some ente-nt `thus to apprise the customer that the machine has properly operated and that now the package 15 may be removed, and also to; thc convenience oi the attendant in revstoring the machine again to an operable condition with a package therein. For this purpose a flat slidable door-opening finger 56 is guided between the inner and outer bottom walls 11 and et along the right hand marginal flange et the inner wall 11 at one edge ot this The plate 89 may then display' the door is unlocked, as shown in Fior. 5, sliding movement is imparted `to the finger 56 to push the door open by means of a wire spring 60 which at one of' its ends is lined in a transverse slot in linger 56 near the rear end there-` while the tree end of this spring` abutjs nainst 'tl rear wall 1 ot the casing bon.

lt/Ieans are provided operable only by an authorized person `for restoring the machine to an operable condition to eifect another sale. such means comprising a device for releasing the locking pawl 3ft from its locking engagement with the locking lever 29. Such device may conveniently and inexpensively be a keyeoperated device similar in that respect to a keybperated loclr or, so tar as the present invention is concerned, such device could be ot' a kind rendered operable only through the carrying out of certain movements and being in that respect similarl to a combination loclr. In the construction shown in the drawings, the outer door wall 6 is pro-` vided at its upper left hand corner with an outwardly proj ecting tubular boss 61 to provide a supporting housing for the device which is to be operated tor releasing the locke ing pawl 34. The casing boss 61 has iitted and secured therein a key-operated lock 62 having a key-hole .63, and this lock per se may be of any suitable ,construction which has a rotatable element, and the loclr 62 is of a standard commercial type having a rotatif able element which may be unlocked and ro.- tated by means of a hey. In the construction shown, a lever 64, located between the inner and outer door walls 8 and 6, i5 carried by the inner end ot the rotatable key-operated element ot the lock 62 and may be secured thereto by means of a pair of screws 65 (Fig.

5). In carrying out the invention, the fund-i tion ot the loch 62 and its lever 64 is to un: lock the operatingmechanism of the machine when such mechanism is in its locked Condition shown in Fig. 5, thereby to restore such mechanism to its normal operable condition shown in dotted lines in Fig. 1, and as also shown in part in Figs. 2., 3 and 4. In both the normal or operable condition of such mechas nism shown in Fig. 1 and the locked condition thereot shown in Fig. 5 the lock lever 64 is in the same or normal position thereof which is shown in dotted lines in Fig. 1 and in full lines in Fig. 5. In this normal position V0f the lock lever 64 its upper end abuts against the adjacent flange ci theiouter door wall 6 and its lower or operating end projects downwardly at the right hand side of and inover-A lapping relation to the upstanding releasing arm of the locking pawl 84. It will be noted that in Fig. 1 the operating end of the loclr lever 6d and the releasing arm of the released locking pawl 34e are in spaced relation, thereby to provide for the automatic spring pressed movement ot this pawl to its locking or engaging position shown in Fig. 5, 1n

los`

ual

which its releasing arm is in close proximity tothe operating arm of the lock lever' 64. The usual locking mechanism of the lock 62 is effective to lock the operating lever 64 at .the normal position thereof shown in Figs. l

and 5.' When the lock 62 per se has been unlocked by means of a proper key inserted therein, then such key may be rotated thereby to impart rotative movement to the operating lever 64 in a clockwise direction as viewed in Figsl and 5. Obviously this clockwise rocking movement of the lock lever 64 will rock the locking pawl 34 in an opposite vor counter-.clockwise direction against the vtension of its spring 36 from the engaged or locking position thereof shown in Fig. 5 to the released or disengaged position thereof shown in Fig. 1. When the lock lever 64 is thus operated to cause it to operate and disengage the locking pawl 34 from the upper end of the locking lever or controlling lever 29, all of the other parts of the operating i mechanism, hereinbef'ore described, between the door walls 6 and 8 will be automatically returned from their operated and locked positions shown in Fig. 5 to their original normal positions shown in Fig. 1, in readiness for a subsequent vending operation, as will presently more clearly appear. Thus it will A34 to perform its locking function as shown in Fig. 5.

When the locking pawl 34 is released, as above described, thereby to release the locking lever 29, the springs 24 and 33 will `iointly cooperate, because of the interengaging connection between the adjacent ends of the lower and upper levers 22 and 29, to rock both of these levers away from the coin-operated position vthereof shown in Fig. 5 to their norvrmal operable positions shown in Fig. 1. It

will be remembered that with the stop shoulder of the coin-carrying plate 39 abutting against the stop ,lug 32 of the locking lever 29, the lower shoulder 48 will be spaced above the upper edgel of the coin 18, which, in the construction shown, then remains at the position thereof appearing in Fig. 5. When the leversl22 and 29 areset free to be activated by their springs the inclined cam face 26 on he upper end of the lower lever 22 will exert a cam action against the edge of the coin 18 andthereby will litt the coin towards the spaced shoulder 48. During this initial litt- Ving of the coin 18 by the cam face 26 the stop lug or locking lug 32 of the locking lever 29 is being withdrawn from the shoulder 55, this spring-actuated movement of the locking lever 29 continuing until its locking lug 32 releases the coin-carrying plate 39, whereupon the latter will be immediately returned by its spring 42 to its uppermost or normal position shown in Fig. 1. In this spring-actuated movement of the coin-Carrying plate 39 its toe 50 engages the lower right hand edge portion of the coin 18 and lifts the latter back to its original position in which it is largely exposed through the coinrecciving opening 38, as will be readily understood by an inspect-ion of Fig. 1. lVhen the coin has been returned to its upper position, it may be readily removed by the authorized attendant through the coin opening 38, and such removal of the coin may be facilitated by inserting, from the back of the open door, any simple device or instrument through an aperture 66 provided centrally of the outer opening 38 in the inner wall 8 of the door, this opening 66 also serving another purpose, as will presently be explained.

it will now be evident that the space appearing in Fig. 5 between the coin plato shoulder 55 and the locking lcvcr stop lug 32 serves a double purpose, in that it provides for the gradual inward movement ol the locking lug 32 while the coin-carrying plate 39 is still moving downward and operating this lever by means of the coin 18, and also in that such space, by permitting a slight return movement of the coin-carrying plate 39, provides for the initial lifting of the coin 18 by the cam tace 26, as above described. It is further to be noted that with the locking lever 29 locked by the locking pawl 34 (Fig. 5), this lever, by reason of the engagement of its tongue or tooth 30 with the left hand tooth 28 of the latch lever 22 will thereby lock the latter lever against independent return movement to its locking position, thus rendering it impossible for the door 6 to become accidently or inadvertently relocked in closed condition prior to the operation of the lock lever 64 by means of lthe proper key inserted into the lock 62, as above described, and in the meantime the door 6 will be held partly open by the spring pressed door-opening linger 56 so that the door cannot be kept closed. rlhis may save the attendant the pos sible trouble of having lirst to pull down the handle knob 40 to unlock the door of the empty machine and also will serve as a. reminder to him to operate the lock 62.

Means are also provided to prevent the possibility of the closing and rel cking of the door 6 prior to the replenishing olf the magazine chamber with another package to be vended, such means possibly saving the attendant having to reinscrt the coin and operate the machine in order to open the locked door, and also serving as a reminder to him to insert another package into the magazine lll.)

fit

chamber. ln the embodiment of the invention shown, a stop bar 67 (Figs. 2 and 4) is pivoted at one of its ends, by means of jour.- nals 68 thereon, between a pair` of spaced bearing brackets 69 shown as secured by means of screws to the inner side of the outer rear casing wall 1. This swinging stop bar 67 may occupy either of two positions, one ot which is itsupstanding position between the outer and inner rear walls 1 and 14 of the casing box, is shown in full lines in Figs. 2 and 4, and the other position of which is the horizontal forwardly extending or projecting position thereof shownin dottedilines in llig. 2. The free end portion of the bar 67 carries a stop collar 7() and has a rounded end projecting beyond this collar as shown.

rllhe rear inner wall 14 is provided with a long vertical slot 71 to provide for the torkward and downward swin o'ing'movement of the stop bar G7 and also foiiins a stop therefor at the horizontal position of this bar, the upper end portion oi this slot being of T shape for the free passage ot the stop collar 70. The stop bar G7 is continually urged to move from its upright to its projected horizontal position by means ot a coiled threewarmed wire spring 7 2, the coils of which encircle the journals 68, the upper double or looped arm of which engages at the back of the stop bar 7, and the lower ends or" the downwardly eX- tending tree arms ot which abut against the back of the inner wall 14.

rlChe package 15 holds the stop bar 710 in its" upright position against the tension ot its springs 72 by the engagement of. the back of the package with the forward edge ot the stop collar 7 0, as shown in Fig, 2. Vifhen the package l5 is removed 'from the casing b the stop bar 67 then being setirec, will automatically assume its forwardly projecting position, and it is ot alength sui'licient to eng the inner wall 8 oi the open door G and will act as a positivo abutment to prevent the door from being fully closed, so that then the door cannotbe locked and will be held partly open. by the spring-pressed `door-opening` fin 'a 56, ln the particular construction showmthc rounded tree end oi; the stop` bar G7 will enter and project through the aperture in` the inner wall 8 of the door, while the stan) collar 70 will torni an abutment at the back ottl wall to prevent the locking ot the door. lt will thus be seen that the door (l after ing been unlocked and the package l moved cannot again be relecl other package has been placed in n A Zine cha aber oit' the casing box to hold up the stop bar G7.

llt/*hen the door (l is in the locked condition, shown in llip l to 4 inclusive, the in wall 8 ot the door holds the package back againt or in proximity to the rear inner eosin-'r wall 14, with stoo bar (37 held at i s i i its upright position 2), ln the particular construction shown, the T-headed spring-holding lug 43 which projects from the rear face oi' the inner door wall 8 engages the front of the package 15, and an additional lug 73 (Fig. 4) ot equal length and simi,- larly punched back from the wall 8 may be provided to be engaged by the 'front ot the package 15 adjacent its other side, for thereby holding the package 15 squarely in position against the tension ott the spring 7 2 ot the stop bar 67. Ubviously any desired nurnber of the lugs 73, located wherever desired, may be provided.

ln carrying out the invention, as a feature thereoil and according thereto, means are provided tor effectively guarding against the theft of the vending machine as a whole, together with its contained package 1t, or with its contained coin, such means also, according to the invention, providing for supporting and guarding against the theft ci' a plurality of these machines arranged side by side in a horizontal series and including` cooperating features of the machines themselves and of a support in common therefor. rlhis feature oi' the invention has been made the subject of a copending divisional application, Serial llo. 231,311, iiled November 5, 1927, which became Patent No. 1,718,249, dated June 25, 19529.

ln the construction shown (Figs. 2, 4 and 6) the rear wall 1 of the casing ot each of the vending machines (shown in Fig, 6 as eight in number) tits against the front side or tace of an upright supporting and securing plate 74, the rear side or back ot' which is openly and freely accessible; and the bottom wall 4 of each ot' the vending machines rests upon a horizontal supporting plate 7 5 which is 'formed in one piece with the upright plate 74, thereby to iorm an L-shaped supporting and securing` plate ior all ot the machines. ThisL-shaped plate is secured in iixed position upon the top ot a. fined support 76 which may be, for example, the top ot a counter' or a shelf or the like, by means oft suitable securing devices shown as screws 77, one of which appears in Fig. 2, passing downwardly through the horizontal plate 7 5 into the sup'- port 7 6 and having their heads covered by the bottom wall 4 of the machine casing, so that these screws are inaccessible 'for removal while the machine is in place on the plate 75.

The rear wall 1 or the vending machine is provided with a lower rearwardly proiecting iat-headed stud. 7S, the head ot which is spaced from this wall to an extent equal to or little more than the thickness ot the upright plate 7 4, and the inner reduced or shouldered end of the shank ot this stud passes through and is riveted or upset at the inner side ot the casing wall l. The rear casingwall 1 of eachvending machine is also provided with an upper hat-headed stud 79 ot somewhat larger dimensions and of ico greater strength than the lower stud 78 and the head of which is spaced a greater distance, for example, about twice the distance of that of the lower stud 78, from the bach oic the rear casing wall l, thereby to provide a longer shank for this upper stud, the inner' reduced end of the shank of this stud also passing through and being riveted at the inner side ot' the casing wall l.

The upright supporting and securing plate 74 has therein a lower horizontal series of key-hole slots 8.0 which are shown as equidist-antly spaced from one another a distance substantially equal to the width of the rectangular casing bon of any one of the vend- K ing machines (Fig. 6), these key-hole slots having their small ends directed downwardly and being equal in number to the number of the vending machines to be accommodated on the vertical plate 7 4. This upright plate 74 is also similarly7 provided with an upper horizontal series ot key-hole slots 8l with their small ends also directed downwardly. The distance or spacing between the centers of the enlarged circular upper ends of the lower key-hole slots and the enlarged circular upper ends of the upper key-hole slots 8l is the same as the spacing or distance between the centers of the lower studs 78 and ythe upper studs 79 carried by the rear wall stud 79 is then spaced rearwardly from the` upright supporting plate 74.

Locking means are provided to prevent the unauthorized disengagement of the studs 78 and 79 from -the key-hole slots 8O and 81, and in the embodiment of the invention shown in the drawings, such'means is common to all of the vending` machines in the series thereof. In the particular construction shown, a straight locking bar 82 normally extends horizontally at the back of the upright plate 74 immediately above and in locking engagement with the shanls of the upper studs 79 within the space provided between the flat heads of these studs and such plate (Figs. 2 and G). This locking bar is shown as pivoted at one of its ends on the upper right hand corner portion of the upright plate 74 by means of a pivot stud or rivet 83, so that thereby this locking bar may be swung upwardly out of engagement with the upper studs 79 or downwardly into engagement therewith, as is shown in the drawings.

A key-operated lock 84 secured, for exam ple, by means of rivets 85, on the back of the upright plate 74 below andv adjacent to the other or free end of this locking bar, has a bolt 86 which may be withdrawn by means of a key for the lock 84 or it may be horizontally projected as shown in Fig. G. The locking bar 82 carries a downwardly projecting catch or keeper 87, shown as a separate piece riveted to the bar, and having at its lower end a hook or shoulder to be engaged by the lock bolt 86 or to be disengaged thereby. A clip 88 on the back of the plate 74 and shown as riveted thereto is engageable by the outer side of the lower end of the catch 87 to prevent the possibility of this catch being sprung outwardly out of its engagement with the lock bolt 86. It will now be evident that only an authorized person having a proper' key for the lock 84 will be able to remove any one of the vending machines from its support.

It is obvious that various modifications may be made in the construction shown in the drawings and above particularly described, within the principle and scope of the invention as deiined in the appended claims.
